Mam, dou have any PPT regarding molecular biology, plz answer
I have many PowerPoints concerning many different topics in molecular biology. Is there a specific topic you're interested in?
Thank you
thank you
Very helpful thank you so much
Straight to the point better than my instructor 😅
Wow, that really helps alot. I don't think I need a education for that.
Thank you very much. your video is really easy to understand and helpful for me. Keep it up dear
Thanks a lot for making such short and too precise video. 🫶
Thanks for the help! I have a microscope myself and this video really helped me with the glass slides.
I’m not sure if we’re supposed to be able to hear but halfway through the video the audio stops playing I can’t hear anything
Wonderful video! I will caution students and researchers that one of these "rules" is often broken. In scientific publications and software, two "paired" strands are often written together (one above the other), but *without* the 5'/3' labels. This makes it very easy to forget that the bottom strand is actually 3' → 5' and can result in confusion and accidental propagation of "reverse" sequence (without realizing it). So I recommend that you imagine the 5' / 3' label on the top strand and the 3' / 5' labels on the bottom strand to avoid confusion. Also, when copying/pasting sequence info, use the top strand as much as possible (and use software to generate the reverse-complement as needed).
LEGEND!
Thanks sir for making it clear 🙏🏼🔥
Interesting procedure but that egg under the microscope at the end will make me cringe every time. - CM
Thank you, I was so confused about this thing 😢 thanks
....
Thank you so much,the thing is i use to write it in wrong way because i don't flip the sequence and my teacher does not clear that thank you
OMG THIS MAKES MY LIFE MUCH MORE EASIER!!! THANK U VERY MUCH
Great video! I have my first micro quiz tomorrow and you’ve absolutely helped. Thank you.
You're very welcome!
If the CFU on the plates are all outside the greater than 30 but less than 300 range, do you have to redo the serial dilution?
In the real world, yes. It probably means that something went wrong with your dilutions. If you are in my course, however, I'm more interested in your understanding the concepts than having you do this over and over. However, you are expected to acknowledge that you *know* that you're not using a countable plate but that you do not have a choice under the circumstances.
One of the clearest and most concise explanations. Thank You!
I am getting lost in the calculation. Would please make more samples of calculations?
I will try to make another video of example soon.
Thank you very much very informative video. kindly tell me how to pack culture of nitrifying bacteria in sashay or a bottle actually i am asking about the media some people pack bacteria in powder form how they do it?
Miss can you tell me the direction of these sequence CTGACG
All nucleotide sequences are written from the 5' to the 3' end. So, in your case, the sequence would be 5'-CTGACG-3'.
@@ashabrunings3383Miss then how to find in mRNA
What is the last thing you applied to the plates?
parafilm to wrap. then nail polish ink as a marker based on medium
you deserved my subscription.. i love them, clear and compact. good job
Awesome, thank you!
Would i be able to send you some pictures of my colonies in order to help identify them?
I could help with describing colony morphology but there is no way to provide an identification of a bacterium based on *just* the colony morphology.
From colony morphology can we identify the bacteria name?
Not usually. There are many different bacteria that have the same or very similar colony morphology. But it is a start and it can be used to exclude certain bacteria. For example, if you were wondering if your bacteria might be Bacillus cereus and you get small, round yellow colonies, they're definitely *not* Bacillus cereus.
Great video Ms.Brunings!! Personally, I found this activity fun And interesting. Keep up the hard work. 👍👍 Don’t forget to add friends. 😂😂
Lol Asha! I have two dogs. I feel like the UV light is going to be well used even after this At-Home lab.
:-D That little UV light may be my most favorite thing in that bag. It's so adorable. But then again, so is the microscope.
Great job professor
Thank you Lucas.
Great Video
